I'm trying to understand how to deploy Zeppelin where there is more than one Zeppelin server. I've seen mention in various places (e.g. [here (around minute 19|https://www.youtube.com/watch?v=J6Ei1RMG5Xo)] (or here: HA Section) that is should be possible but I cannot find documentation about how. My case is that I both want HA and I want to be able to scale with demand. I'm unclear how to off-board that configuration (e.g. the notebook authorization conf) to a common location such as database so that it can be shared by the application server instances. It seems like the configuration is local to the instances or maybe I'm just missing something? In my case the plan would be to use s3 as the notebook storage (which I've got working) but I'm unclear how to put the configuration in a common location.
